摘要
本文建立了一个信号博弈模型，在该模型框架下实证研究了大学教育的人力资本积累效应对大学生收入溢价的贡献以及高校扩招对大学生-非大学生收入差距的影响。基于模型的结构估计（structural estimation）证明该模型能很好地拟合大学生和非大学生的工资分布。模型的模拟结果表明：（1）大学教育的人力资本积累效应约能解释大学生工资溢价的72％；（2）与基于劳动力供给角度的分析不同，高校扩招可能通过劳动力市场歧视加剧大学生一非大学生的收入差距。
We establish a model of signaling and explore the contribution of human capital accumulation to college wage premiums, as well as the effect of university enrollment expansion to the college-non-college wage differential. Results from the structural estimation indicate that the model performs very well in fitting the wage distribution. Counterfactual simulation suggests that （1） human capital accumulation accounts for nearly 72% of the college wage premium in China; （2） unlike the analysis from the perspective of labor supply, under very weak conditions the model shows that the university enrollment expansion enlarges college-non-college wage differentials by way of statistical discrimination.
